Billing tips

Verify facility vs non-facility setting before billing, as this affects reimbursement significantly
Impact: $118.71 difference between non-facility ($467.73) and facility ($349.02) rates
Document the specific indication for exploration (e.g., pathologic nipple discharge character, duration, laterality) to support medical necessity
Impact: Prevents denials for lack of medical necessity, which account for approximately 30% of 19110 claim denials
Do not bundle 19110 with duct excision codes (19301) if both exploration and excision are performed; these are distinct procedures
Impact: Prevents unbundling denials while ensuring appropriate payment for both services when documentation supports separate procedures
When performed with breast biopsy or other procedures, append modifier 51 to the lower-RVU code
Impact: Ensures proper sequencing and payment hierarchy; improper modifier use can result in $100-200 underpayment
Submit operative report with initial claim when bilateral modifier 50 is used, as payers often require documentation upfront
Impact: Reduces denial rate by 40% and accelerates payment by avoiding automatic medical review delays
Verify that any imaging studies (mammogram, ultrasound, ductogram) are documented in the medical record prior to exploration
Impact: Supports medical necessity determination and step-therapy requirements many payers impose before authorizing surgical exploration

Frequently asked questions

What is the Medicare reimbursement rate for CPT 19110 in 2025?

The 2025 Medicare national average reimbursement for CPT 19110 is $467.73 in non-facility settings and $349.02 in facility settings. The total RVU is 14.46, consisting of 4.44 work RVU, 8.9 non-facility PE RVU (5.23 facility PE RVU), and 1.12 malpractice RVU.

Can CPT 19110 be billed bilaterally with modifier 50?

Yes, CPT 19110 can be billed with modifier 50 when bilateral nipple exploration is medically necessary and performed during the same operative session. Documentation must support the medical necessity for exploring both nipples, typically bilateral symptoms or findings. Bilateral billing typically reimburses at 150% of the unilateral rate.

What is the difference between CPT 19110 and 19301?

CPT 19110 is for nipple exploration only, a diagnostic procedure to investigate abnormalities. CPT 19301 is for mastectomy, partial (including nipple excision), which involves actual removal of tissue. Code 19110 is used when the surgeon explores but does not excise the nipple or significant breast tissue.

Does CPT 19110 require prior authorization from insurance?

Prior authorization requirements vary by payer. Many commercial insurers require prior authorization for CPT 19110, particularly when imaging has not been performed first. Medicare typically does not require prior authorization, but medical necessity must be documented. Always verify specific payer requirements before scheduling the procedure.

Can CPT 19110 be billed with a breast biopsy code?

Yes, CPT 19110 can be billed with breast biopsy codes if the procedures are distinct and performed at separate sites or through separate incisions. Append modifier 59 or XS to indicate a distinct procedural service. Documentation must clearly show why both procedures were medically necessary and performed as separate services.

What diagnosis codes support medical necessity for CPT 19110?

Common supporting diagnosis codes include N64.52 (nipple discharge), N60.01-N60.09 (solitary cyst of breast), N63 (unspecified lump in breast), and R92.8 (other abnormal findings on diagnostic imaging of breast). The diagnosis must justify the need for surgical exploration rather than continued observation or imaging.

What is the global period for CPT 19110?

CPT 19110 has a 90-day global surgical period. This means routine post-operative care for 90 days after the procedure is included in the reimbursement. Any unrelated procedures during this period require modifier 79, while related returns to the OR require modifier 78. E/M services during the global period are typically not separately billable unless unrelated (modifier 24).
